Topic:

Java Programming Language;;

If I am not using Applet to display standalone program result from Java at command line in HMTL page
by IE. , i mean use back the orginal vendor provide Chartviewer to display Chart in HTML. How I should convert my code in HTML
THe following easy HTML code could not run the simplearea.class code in HTML of my IE
because I specified it using Applet.

The code attahced is the demo example for barchart named "simplearea.java", I run it at
commandline that is not issue at all with it ChartViewer provide by software vendor. BUt
it can not run in HTML paga in IE because I don't know how to write a code in HTML to include
the ChartViewer like Applet.. IF using Applet, I need to modify a lot code in the exmple of
"simplearea.java". Please advise how to display standalone Java program result in HTML page in IE
instead of displaying the standalone program result at my windows only because I need to put it in
my domain name website to show it to other windows Vista users
